To change mobile number in Messenger, you must update your contact information through Facebook's Accounts Center, not inside the Messenger app itself. The official method involves adding your new number and then removing the old one, with SMS confirmation required for the new number and a possible password prompt when deleting the old one.
Where to change your mobile number in Messenger
Messenger does not provide a direct setting to change your phone number within the app. The documented place to add or remove a mobile number is Facebook's Accounts Center. This is the same system used across Facebook, Messenger, and Instagram, so changing your phone number on Accounts will update it for all linked accounts if you choose.
Navigate to Accounts Center contact info
Follow this exact path from within the Messenger app:
- Tap your profile picture in the top right corner.
- Select Settings & privacy.
- Tap Settings.
- Choose Accounts Center.
- Under Account settings, tap Personal details.
- Tap Contact info.
Add your new mobile number
- Tap Add new contact.
- Select Add mobile number.
- Enter your new mobile number.
- Choose the accounts (Facebook, Messenger, Instagram) you want to add it to.
- Enter the SMS confirmation code sent to your new number.
- Tap Next, then Close.
Remove your old mobile number
- In the same Contact info section, select your old mobile phone number.
- Tap Delete number.
- Tap Delete to confirm.
- If prompted, re-enter your Facebook password to verify your identity.
Troubleshooting the confirmation code
If the SMS confirmation code does not arrive when adding your new number, check that mobile texts are turned on for your device. Ensure your phone can receive SMS messages from short codes and that you have not blocked texts from Facebook. Verification serves as a protective measure against potential fraud or unauthorized access attempts. If the problem persists, try restarting your phone or requesting the code again after a few minutes.
